You also won’t be allowed to drive with anyone under 20 in the car unless there’s a licensed driver who is 25 or older in the car with you both.
If you’re caught driving outside of curfew, you could be ticketed. If you receive more than two driving points on your license within the first 12 months, you could even have your license suspended or revoked, so it’s best to only drive within the allowed time, just to be safe.
